Abstract

Description

CONNECTOR FOR INFLATABLE LINE COAXIAL CABLE FIELD OF THE INVENTION The present invention relates to electrical connectors and more particularly to axially compressible connectors for inflexible or semi-rigid line coaxial cables.

DESCRIPTION OF RELATED TECHNOLOGY Coaxial cables are commonly used in the cable television industry to carry cable television signals to television sets in homes, businesses and other places. An inflexible line coaxial cable can be used to carry signals in distribution systems outside these sites and a flexible coaxial cable is then frequently used to carry the signals within the interior of these sites. The inflexible or semi-rigid line coaxial cable is also used where a high degree of radio frequency shielding is required. The inflexible line cable includes a solid core of wire or inner conductor, typically of aluminum or aluminum coated with copper, surrounded by a tubular solid outer conductor. The outer conductor is commonly made of copper or aluminum. The dielectric material or insulation separates the internal and external conductors. The outer conductor is covered with a liner or plastic cable cover to provide protection against corrosion and wear due to atmospheric agents. One type of connector for semi-rigid coaxial cables includes the direct solder connection of the connector to the outer conductor of the cable. See, for example, U.S. Patent Nos. 4,921, 447 and 5,232,377. The soldering connection provides, in part, the mechanical connection of the connector to the external conductor. Such a direct solder connection, however, has often been a production problem because of the complex equipment required for welding and the difficulty in operating the complex equipment. Another type of inflexible line cable wire connector uses radial compression fixation to electrically and mechanically connect the connector to the cable. Typically, a sleeve inside the connector is compressed by the fixing tool. The sleeve may have slots, grooves, threads and the like to assist in the mechanical connection between the sleeve and the outer conductor of the cable.

See, for example, U.S. Patent Nos. 4,408,821; 4,469,390; 5,120,260 and 6,042,422. Fixation by radial compression however, frequently does not apply the compressive force uniformly to the external conductor or alternatively to the outer tubular cover of the outer connector. Said non-uniform compression can form channels for the infiltration of moisture towards the connection of the coaxial cable and consequently leading to the degradation of the signal carried by means of the cable. Threaded cable connectors have been used to provide the most uniform compression of the connector. See, for example, U.S. Patent Nos. 5,352,134 and 6,019,636. However, threaded connectors are often more time consuming to install because of the rotational movement required to complete the threaded connection. In addition, an installer for threaded connectors must often carry many different sized wrenches to accommodate cable connectors of different sizes, which also complicates the installation process. To overcome the difficulties of the pressure and threaded connectors, different designs of axially compressible connectors have been used.

U.S. Patent Nos. 4,408,821 and 4,452,503 disclose a connector with a slotted tubular sleeve radially compressing a clamping ring upon axial compression of the connector. The clamping ring has grooved nails that make grooves in the external conductor and longitudinal channels that lock with the outer conductor. Said arrangement, however, mechanically deforms the external conductor, which can lead to loss of the signal. further, the design does not adequately protect against moisture entering the connector because the total circumferential surface of the outer conductor is not necessarily coupled with a clamping ring. An attempt to provide a better sealing mechanism in the related application, U.S. Patent No. 4,540,231, employs glue to provide a seal. The use of glue, however, further complicates the installation and construction of said connector. U.S. Patent Nos. 4,596,434 and 4,668,043 disclose a tubular housing with a toothed interior which is radially compressed by a bushing upon axial compression of the connector which forces a coupling nut onto the hub. The teeth make grooves in the external conductor to provide the mechanical and electrical connection in it. The bushing may also contain an O-ring which acts as a seal between the bushing and the outer conductor. Such designs, however, still require significant mechanical deformation of the outer conductor which can lead to signal loss. U.S. Patent No. 4,834,676 discloses a splice sleeve with inner tabs or spines and a longitudinal slot. The tines deform the outer conductor by compressing the splice sleeve by means of a tool to axially compress the connector. This design depends on the longitudinal groove that is substantially closed after compression of the splice sleeve for Provide a seal for the connector. However, said design is not effective against moisture filtration. As such there is a need for an easy-to-connect connector for inflexible line cables that is simpler to connect and provides the proper mechanical and electrical connections. In addition, there is a need to provide a connector for an inflexible line cable that provides an effective seal against moisture filtration from the external environment without substantial deformation of the outer conductor of the coaxial cable.

BRIEF DESCRIPTION OF THE INVENTION The present invention provides an environmentally sealed, quick connect connector for inflexible or semi-rigid line coaxial cables. The connector includes a seal ring and a sleeve, with a sealing device. Upon axial compression of the connector to close and secure the connector to the coaxial cable, the seal ring and the sleeve slidably engage and force the sealing device towards the outer cable jacket of the coaxial cable to provide an environmentally sealed portion of the coaxial cable. same. In one aspect of the present invention the sleeve contains a circumferential groove at the distal end of the sleeve, the end of which is close to the seal ring. Upon axial compression of the connector, the sleeve and seal ring slidably engage to force an inner portion of the distal end of the sleeve onto the cable jacket to environmentally seal the connector therein. In another aspect of the present invention the sleeve contains a notch at its distal end and an O-ring placed within the notch. When the axial compression of the connector occurs, the sleeve and the seal ring engage in a Slidable to compress the O-ring on the cable cover and form an environmental seal there. Upon axial compression of the connector, the proximal end of the sleeve, which is opposite the distal end, slidably engages a splice sleeve having separate nails. The nails of the splice sleeve compress radially inward to secure the splice sleeve to the outer conductor of the coaxial cable. The connector also includes a post that prevents collapse of the external conductor upon compression of the splice sleeve. The post, the splice sleeve and the sleeve are generally contained within a connector collar. When axial compression occurs to close the connector, an environmental seal is formed between the sleeve and the collar to prevent migration of moisture there. In still another aspect of the present invention there is provided an environmentally sealed connector for inflexible or semi-rigid line coaxials. The connector includes O-rings to provide environmental seals when securing the connector to the coaxial cable. An O-ring is placed inside a notch of a cylindrical sleeve. This O-ring couples on a cover of the cable of the coaxial cable to form an environmental seal there. By securing the connector to the coaxial cable, the sleeve couples to a separate splice sleeve. The separate splice sleeve compresses radially inward to secure the splice sleeve to an outer conductor of the coaxial cable. The connector also includes a post that prevents collapse of the outer conductor by compressing the splice sleeve. By securing the connector to the coaxial cable, an environmental seal is also formed between the cylindrical seal and the collar to prevent migration of moisture there.

DETAILED DESCRIPTION The present invention is directed towards a connector for inflexible or semi-rigid line coaxial cables. The connector is configured to be capable of axially compressing around an inflexible line coaxial cable to provide the mechanical and electrical connections to the coaxial cable. In addition, when axial compression occurs the connector environmentally seals the coaxial cable to protect against moisture leakage that may adversely affect the operation of the coaxial cable. Figure 1 represents a perspective view, in partial section, of the connector 10 of the present invention. The connector 10 includes a seal nut 12, a collar 14, a post 16, a splice sleeve 18, a sleeve 20 and a seal ring 22, inter-related as shown. The connector 10 is a quick connect RF connector for use with an inflexible line coaxial cable 24 and closes upon axial compression occurring. The coaxial cable 24 includes a central, elongated cable conductor 26 capable of providing electrical signals therethrough. The central conductor 26 is typically formed from a conductive metal, such as copper, copper-plated aluminum, copper-plated steel and the like. Surrounding the central conductor of the cable 26 is a cable dielectric 28 which insulates the center conductor of the cable 26 to minimize the loss of the signal. The dielectric of the cable 28 also maintains a separation between the central conductor of the cable 26 and the external conductor of the cable 30. The dielectric cable 28 is often a plastic material, such as polyethylene, a fluorinated plastic material, such as a polyethylene, a material fluorinated plastic, such as a polytetrafluoroethylene, a glass fiber interlacing and the like. The outer conductor of the cable 30 is typically a metal, such as aluminum or steel, and is frequently extruded to form a hollow tubular structure with a solid wall having a smooth outer surface. The cable jacket 32 surrounds the outer conductor of the cable 30 to further seal the coaxial cable 24 and is typically a plastic, such as polyvinyl chloride, polyethylene, polyurethane, polytetrafluoroethylene and the like. As shown in Figure 1, a portion of the cable cover 32, the outer conductor of the cable 30 and the dielectric of the cable 28 are withdrawn from the proximal end of the coaxial cable 24. As used herein, "proximal" refers to a direction generally longitudinally towards the spigot terminal 40. Upon axial compression of the connector 10, the exposed portion 27 of the central conductor of the cable 26 is slidably coupled with the spigot terminal 40. The spigot terminal 40 is secured within the nut of seal 12 by means of spigot holder 50 and base 52 and secured within collar 14 closing collar 54. An O-ring 13 provides an environmental seal between seal nut 12 and collar 14. Moreover, parts of the cover of the cable 32 and the dielectric of the cable 28 are further away from the proximal end of the coaxial cable 24 to provide an exposed portion 31 of the external conductor of the cable 30. The post 16 has an elongated tubular portion 56 adapted to engage an internal wall of the exposed portion 31 of the external conductor of the cable 30. The post 16 has a flange 58 at the proximal end thereof and has flanges 60 at the proximal end of the elongated tubular portion 56 The post 16 comprises a conductive metal, such as aluminum or bronze. As shown in Figure 2A which is a cross-sectional view of the connector 10 in an open position, the flange 58 and the flanges 60 are configured to secure the splice sleeve 18 with the collar 14. Figures 3A and 3B are perspective views of the splice sleeve 18. The splice sleeve 18 has a hollow tubular flange 62 at the proximal end thereof. The inner portion 63 of the flange 62 is configured to couple in a manner confined to the flanges 60 of the post 16. An outer portion 64 of the flange 62 is configured to fit in a confined manner to an inner portion of the collar 14. The splice sleeve 18 has a plurality of spaced nails 66. The separate nails 66 have a plurality of projecting shoulders 68 extending circumferentially from the interior portions 70. Desirably, the shoulders 60 are threads projecting inwardly. As described in greater detail hereinafter in conjunction with Figures 2B, the flanges 68 are configured to securely engage the exposed portion 31 of the outer conductor of the cable 30. In addition, the spaced apart nails 66 have an inclined surface 72 that provides a Distant tapering of the separated nails 66. The splicing sleeves 18 comprise a conductive metal, such as aluminum or bronze. The sleeve 20 is a hollow tubular elongate cylinder made of a deformable material, such as a plastic material. Useful plastic materials include acetal resins such as polyoxymethylene type acetal resins, such as Derlin® available from DuPont de Nemours and Co. The distal portion 34 of the sleeve 20 has an annularly formed groove 36 extending longitudinally toward the wall of the distal portion 34. The slot 36 is configured to receive the proximal end 38 of the seal ring 22 and is described below in conjunction with Figures 2A and 2B. As shown in Figures 2A and 2B, adjacent to the distal portion 34 of the sleeve 20 is an indentation 35 extending circumferential shape which is adapted to retain an O-ring 34. The O-ring 74 comprises a resilient material, such as a synthetic rubber, an elastomeric polymer or a deformable plastic. Adjacent to the indentation 35 is an outwardly projecting protrusion 76 which is configured to secure the sleeve 20 within the collar 14 upon closing the connector 10. The proximal end of the sleeve 20 is tapered from both the inner and outer surfaces of the sleeve. 20. The tapered inner surface 78 of the sleeve 20 is designed to slidably engage the inclined surface 72 of the separate nails 66 of the splice sleeve 18. Figures 4A and 4B are perspective views of the seal ring 22, which has a hollow hole therethrough. The distal end 44 of the seal ring 22 has a flange 42 there. The proximal portion 38 of the seal ring 22 has circumferentially extending ribs 46 extending outwardly from the outer wall 48. Desirably, the ribs 46 are threads projecting outwardly. Seal ring 22 is desirably made from a metal, such as aluminum or bronze. The seal ring 22 fits into a cavity within the sleeve 20 and the ribs 46 secure the seal ring 22 there. As shown in Figure 2A, which is a cross-sectional view of the connector 10 in an open position, the coaxial cable 24 is placed inside the connector 10. The exposed cable conductor 27 is placed inside the spigot terminal 40. The exposed portion 31 of the outer conductor of the cable 30 is placed between the post 16 and the splice sleeve 18. The post 16 supports the exposed portion 31 of the outer conductor of the cable 30 to inhibit substantial deformation of the outer conductor of the cable 30 to the closing the connector 10. The proximal end of the sleeve 20 is positioned within the distal end of the collar 14. A tool (not shown) can be used to axially compress the connector 10 to close and seal the connector 10. As shown in the Figure 2B, upon axial compression occurring, which is indicated by the vector AA, the connector 10, the tapered inner surface 76 of the sleeve 20 slidably engages the inclined surfaces. nipples 72 of the splice sleeve 18. The sliding coupling compresses the separate nails 66 of the splice sleeve 18 inwardly after which the flanges 68 abut the exposed portion 27 of the outer conductor of the cable 26 to secure the outer conductor of the cable. cable 26 between the post 16 and the splice sleeve 18.

On the other hand, upon axial compression of the connector 10, the distal portion of the collar 14 slidably engages the distal portion 34 of the sleeve 20 to compress the O-ring 74 to environmentally seal the connector 10 therein. The protrusion 76 of the sleeve 20 slidably engages the groove 80 which extends circumferentially along the internal portion of the distal portion of the collar 14. This sliding engagement of the protrusion 76 and notch 80 securely fixes the sleeve 20 to the collar 14. Further, upon axial compression of the connector 10, the proximal end 38 of the seal ring 22 slidably inserts into an annularly formed groove 36 of the sleeve 20 until the distal portion 34 of the sleeve 20 engages confined with the flange 42 at the distal end 44 of the seal ring 22. The flange 42 serves as a stop to limit movement of the seal ring 22 in the sleeve 20. The engagement of the seal ring 22 in the sleeve 20 forces in a circumferential manner an inner portion 82 of the distal portion 34 of the sleeve 20 on the cable sheath 32 to environmentally seal the connector 10 therein. The ribs 46 of the seal ring 22 engage an internal surface 84 of the annularly formed groove 36 of the sleeve 20 to secure the seal ring 22 within the sleeve 20. The present invention is not limited to providing an environmental seal on the cable cover. compressing a portion of the connector sleeve. In another aspect of the present invention, as shown in Figures 5A and 5B, an O-ring 186 is used to environmentally seal the connector 100 on the cable sheath 132. The O-ring 186 comprises a flexible material, such as a rubber synthetic, an elastomeric polymer or a deformable plastic. Figures 5A and 5B are cross-sectional views of the connector 100 in the open and closed positions, respectively. In the Figures 5A and 5B similar components have similar numbers as described above.

The sleeve 120 has a notch 136 in its distal portion 134. Upon axial compression of the connector 100, the proximal end 138 of the seal ring occurs. 122 slidably engages and compresses the O-ring 186. Upon compression occurring, the O-ring 186 engages the cable cover 132 to environmentally seal the connector 100 there. In another aspect of the present invention, the seal ring 122 has a protruding portion 188 near the flange 142 as shown in Figure 6, which is a partial cross-sectional view of the connector 100 detailing the arrangement of the sleeve 120 and the seal ring 122. The protruding portion 188 is an interference that controls the force required to slidably engage the seal ring 122 and the sleeve 120. However, the present invention is not limited to the use of the portion that 188 protrudes to control the coupling force. Other parameters, such as the size of the notch 136, the height of the ribs 146, the size of the O-ring 186 and the like, can be used to control the coupling force. The flange 142 acts as a positive stop to prevent over compression of the O-ring 186. Various changes to the corresponding structures and methods described above would now be apparent to those skilled in the art. The matter set forth in the foregoing description and the accompanying drawings is therefore offered by way of illustration only and not as a limitation. Accordingly, the particularly disclosed scope of the invention is set forth in the following claims.
